JAMES C. STEEN, OF CINCINNATI, OHIO, ASSIGNOR TO THE CINCINNATI SHAPERCOMPANY, OF CINCINNATI, OHIO, A CORPORATION SHAPING-MACHINE.

Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed May 31,1904. Serial No. 210,619.

To all whom it may concern:

Be it known that I, J AMES C. STEEN, a citizen of the United States, anda resident of Cincinnati, in the county of Hamilton and State of Ohio,have invented a certain new and useful Improvement in Shaping- Machines,of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, which form a part ofmy specification.

My invention relates to shaping-machines,

and more particularly to a shaping-machine provided with a pull-cuthead.

The object of my invention is to so construct and arrange the head andits connection with the ram that the pull of the tool when cutting isexerted against substantially square bearing-surfaces in the solidmetal.

The advantages of my construction will appear as I proceed with myspecification.

In the drawings, Figure 1 is a side elevation of the front end of a ramwith my improved head attached thereto. Fig. 2 is a vertical sectionthrough the same. Fig. 3 is a front elevation of the head and ram. Fig.4 is a partial plan and section of the ram on the line 4 4 of Fig. 3.Figs. 5 and 6 are details, which will be referred to later.

A is the body of the ram, which is provided at its forward end with aboss formed into an annular groove to and an annular shoulder 6. (SeeFigs. 2 and 4.) The forward end of the ram A is bored out to receive atrunnion B, which forms part of a flanged disk C, the rear face of thedisk bearing against the end of the ramA and the flange of the sameforming with the annular groove 0 an annular closed slot in which theone-sided heads of bolts D D fit, which by means of the nuts D clamp theflanged disk in any angular position. The flanged disk C is cut away atthe bottom (see Fig. 2) to receive a key d, having flanges d d, whichengage, respectively, the front face of the flanged disk and theshoulder b on the ram, thus conveying any pull on the disk directly tothe ram, said key being retained in place by a screw d.

The disk C is provided at its forward end or face withvertically-extending ribs E E, provided with flanges or shoulders E E.These flanged ribs E E are embraced by the sides of a hollow box F,which is open at the back and provided with vertically-extending flangesor shoulders ff, which, together with justment of the tool-carrier.

the flanged ribs E E and the sides of the box F, form closed grooves inwhich fit wedges G, by means of which the box F may be'clamped inposition. It is thus apparent that any pull on the forward face of thebox F is borne by the flanges or shoulders E f and the wedges G. Therear face of the box Fis let into the front face of the ring C, spacesbeing left at each side to receive the gibs e 6, (see Figs. 3 and 4,)which are held in place by squareheaded screws 6. These serve to preventany lateral play of the box.

The sliding box F is operated up and down for the down feed of the toolin the usual manner through the screw 9, the gears g g, the shaft it,and the gears h, as described in Letters Patent No. 656,795, of August28, 1900, granted to Steen and Warner, and forms no part of this presentinvention. The operation is apparent from the drawings.

The tool-carrier J is supported on the sliding box F in the followingmanner: The sliding box F is provided with a boss H, which has at itslower side square shoulder H, forming an arc'of a circle extendingthrough an angle of less than one hundred and eighty degrees. J is thetool-carrier and is secured against the face of the box F. The rear faceof the toolcarrier is socketed to receive the boss H, the lower edge ofthe socket being provided with a-square shoulder H, engaging theshoulder H on the boss H. The shoulder H is also formed in the arc of acircle, but extends through an angle of about one hundred and eightydegrees. (See Figs. 2, 5, and 6.) The tool-carrier J is journaled on ascrew-threaded pin K, which screws into the boss H, the axis of thejournal being concentric with the center of the arcs in which theshoulders H.

and H are formed. It is apparent that the diflerence in angle of thearcs in which the shoulders H and H are formed will permit of thetool-carrier being slipped into or out of place by properly shifting iton the journal-pin K. It is not necessary that the angles of these arcsbe as described, it being suflicient that the angles of the two whensummed together shall be less than three hundred and sixty degrees. (seeFigs. 2 and 3) permits of the angular ad- The tool-carrier is bifurcatedat its forward end, and between the bifurcations J J is pivoted atoolholder M on the pin M.

A bolt and slot L and L It is apparent that with the pin M in theposition shown the tool will cut on the return stroke.

From the construction described it will be seen that the pull of thetool is exerted directly on the shoulders H H", E, andf and b, thestrain being thus exerted on solid metal throughout. I find that thisconstruction is very strong and durable and prevents the necessity oftaking up wear and tear by the lightening of bolts.

Having thus described my invention, what I desire to claim as new andcover by Letters Patent is 1. In a pull-cut shaping-machine, incombination with the ram and down-feed box, a boss on the front face ofsaid box, a bifurcated tool-carrier havinga socket in its rear face toreceive said boss, engaging shoulders forming arcs of circles at theedges of said boss and said socket, the sum of the two arcs being lessthan three hundred and sixty degrees, a pin centrally located as to saidarcs secured to said boss and forminga journal for said toolcarrier,means for clamping said tool-carrier in any angular position, and atool-holder pivoted at the forward ends of the bifurcations of saidtool-carrier, substantially as described.

2. In a pull-cut shaping-machine, in combination, the ram, the down-feedbox, a bifurcated tool-carrier rotatably supported with its rear faceagainst the face of said down-feed box, a boss on the face of saiddown-feed box, a socket in the rear face of said tool-carrier to receivesaid boss, engaging shoulders forming arcs of circles at the edgesofsaid boss and said socket, the sum of the angles of said arcs beingless than three hundred and sixty degrees, means for clamping saidtool-carrier in position, and a tool-holder pivoted in the bifurcationof said tool-carrier, substantially as described.

3. In a pull-cut shaping-machine, in combination with the ram, a boss atthe forward end of said ram formed into a radially-extending annularshoulder and an annular groove between said shoulder and the forward endof the min, a flanged disk journaled on the end of the ram, the flangeof the same forming with the annular shoulder and groove in said boss aclosed annular slot, bolts with their heads in this closed slot clampingsaid flanged disk to the ram, vertically-extending flanged ribs in thefront face of said disk, the downfeed box embracing said flanged ribs,its sides being provided with flanges located behind the flanges on saidribs, wedges embraced between said flanged ribs and the flanged sides ofsaid box, a boss on said down-feed box, a

bifurcated tool-carrier journaled on said boss, a socket in the rearface of said tool-carrier to receive said boss, engaging shouldersforming arcs of circles at the edges of said boss and said socket, thesum of the angles of the two arcs being less than three hundred andsixty degrees, means for clamping said toolcarrier in any angularposition, and a toolholder pivoted in the bifurcations of saidtool-carrier, substantially as described.

4. In a pull-cut'shaping-machine, in combinationwith the ram, a boss atthe forward end of said ram, an annular groove in said boss, a flangeddisk the flange of which together with said annular groove on said bossforms a closed annular slot, bolts with their heads in this closed slotclamping said disk to the ram, a key provided with flanges engaging thegroove in the ram and the front face of said disk, the down-feed boxprovided with vertical shoulders engaging similar shoulders on saiddisk, wedges clamping these shoulders in position, a bifurcatedtool-carrier rotatabl y.

supported with itsrear face against the face of said down-feed box, aboss on the'face of said down-feed box, a socket in the rear face ofsaid tool-carrier to receive said boss, engaging shoulders forming arcsof circles at the edges of said boss and said socket, the sum of theangles of said arcs being less than three hundred and sixty degrees,means for clamping said tool-carrier in any angular position, and atool-holder pivoted in the bifurcations of said tool-carrier,substantially as described.

5. In a pull-cut shaping-machine, in combination with the ram, a boss atthe forward end of said ram formed into a radially-extending annularshoulder and an annular groove between saidshoulder and the forward endof the ram, a flanged disk journaled on the end of the ram, the flangeof the same forming with the annular shoulder and groove in said boss aclosed annular slot, bolts with their headsin this closed slot clampingsaid flanged disk to the ram, a key provided with flanges engaging thegroove in the ram and the front face of said disk, vertically-extendingflanged ribs in the front face of said disk, the downfeed box embracingsaid flanged ribs, its sides being provided with flanges located behindthe flanges of said ribs, wedges embraced between said flanged ribs andthe flanged sides of said box, and a tool-carrier and means for securingthe same to said down-feed box, substantially as described.
